Na te WRC-23 e haere ake nei (2023 World Radiocommunication Conference), kei te wera haere nga korero mo te whakamahere 6GHz i te kainga me o waho.
Ko te 6GHz katoa te tapeke o te 1200MHz (5925-7125MHz).Ko te take ko te toha 5G IMTs (hei tuāwhiorangi raihana) ko Wi-Fi 6E ranei (hei tuāwhiorangi kore raihana)
Ko te karanga ki te toha 5G tūāwhiorangi raihana mai i te puni IMT i runga i te hangarau 3GPP 5G.
Mo te IMT 5G, ko 6GHz tetahi atu awhiowhio-waenganui i muri i te 3.5GHz (3.3-4.2GHz, 3GPP n77).Ka whakatauritea ki te roopu ngaru mirimita, he kaha ake te kapinga o te roopu auau reo.Ka whakatauritea ki te roopu iti, he maha ake nga rauemi a te roopu waenga.Na reira, koinei te tautoko roopu tino nui mo te 5G.
Ka taea te whakamahi i te 6GHz mo te aunui pūkoro (eMBB), me te awhina o nga antenna aronga nui-nui me te hanga kurupae, mo te Uru Ahokore Umau (whanui).No tata nei te GSMA ki te kii mo te korenga o nga kawanatanga ki te whakamahi i te 6GHz hei awhi raihana hei whakararu i nga tumanakohanga whanaketanga ao o 5G.
Ko te puni Wi-Fi, i runga i te hangarau IEEE802.11, he rereke te tirohanga: He mea nui te Wi-Fi ki nga whanau me nga umanga, ina koa i te wa o te mate COVID-19 i te tau 2020, i te wa ko Wi-Fi te pakihi raraunga matua. .I tenei wa, ko nga roopu Wi-Fi 2.4GHz me 5GHz, e tuku ana i te torutoru rau MHz, kua tino kikii, e pa ana ki te wheako kaiwhakamahi.Kei te hiahia a Wi-Fi kia nui ake te hihinga hei tautoko i te piki haere o te hiahia.Ko te toronga 6GHz o te roopu 5GHz o naianei he mea nui ki te rauwiringa kaiao Wi-Fi a meake nei.
Te mana tohatoha o 6GHz
I te ao, ITU Rohe 2 (United States, Canada, Latin America) kua whakaritea inaianei ki te whakamahi i te 1.2GHz katoa mo Wi-Fi.Ko te mea tino rongonui ko te United States me Canada, e tuku ana i te 4W EIRP o te AP putanga paerewa i etahi roopu auau.
I Uropi, ka mauhia he ahua aito.Ko te roopu auau iti (5925-6425MHz) e tuwhera ana ki te Wi-Fi iti-kaha (200-250mW) na te Pakeha CEPT me te UK Ofcom, i te mea kaore ano kia whakatauhia te roopu auau teitei (6425-7125MHz).I roto i te Agenda 1.2 o WRC-23, ka whakaaro a Europe ki te whakamahere i te 6425-7125MHz mo te whakawhitiwhiti waea a IMT.
I te Rohe 3 o Ahia-Kiwa-Kiwa, kua whakatuwherahia e Hapani me Korea ki te Tonga te awhiowhio katoa ki te Wi-Fi kore raihana.Kua timata a Ahitereiria me Niu Tireni ki te tono i nga whakaaro o te iwi, a, he rite tonu ta ratou mahere matua ki tera o Uropi, ara, te whakatuwhera i te peera reiti iti ki te whakamahi kore mana, i te wa e tatari ana te peera auau teitei.
Ahakoa ko nga mana o ia whenua kei te tango i te kaupapa here mo te "tuupapa paerewa hangarau", ara ko Wi-Fi, ka taea te whakamahi 5G NR kore raihana, engari mai i te rauwiringa kaiao taputapu o naianei me te wheako 5GHz o mua, i te mea kaore i te raihana te roopu auau, Wi- Ka taea e Fi te rangatira i te maakete me te utu iti, ngawari te whakatakoto me te rautaki maha-kaitakaro.
I te mea ko te whenua tino pai rawa atu mo te whakawhanaketanga whakawhitiwhiti korero, ko te 6GHz he wahanga, he tuwhera katoa ranei ki te Wi-Fi 6E i te ao.
